Hello all. I've just joined the list in hopes of solving a specific
problem.
A few months ago I used WiX to create a fairly simple .msi. Here is the
relevant portion of the .wxs file, with identifying information redacted
(GUID1 and GUID2 represent real uppercase GUIDs):
---START OF CODE---
<Product Name='My Program' Id='GUID1' UpgradeCode='GUID2'
Language='1033' Codepage='1252' Version='1.98.20' Manufacturer='me'>
<Package Id='*' Keywords='Installer' Description="My Program Installer"
Comments='My comments' Manufacturer='me'
InstallerVersion='100' Languages='1033' Compressed='yes'
SummaryCodepage='1252' />
---END OF CODE---
It works fine, but I want to distribute an update and the one I created
refused to install over the top of the old version. After some research, I
changed the .wxs file as follows:
---START OF CODE---
<Product Name='My Program' Id='*' UpgradeCode='GUID2'
Language='1033' Codepage='1252' Version='1.98.206' Manufacturer='me'>
<Package Id='*' Keywords='Installer' Description="My Program Installer"
Comments='My comments' Manufacturer='me'
InstallerVersion='100' Languages='1033' Compressed='yes'
SummaryCodepage='1252' />
<Upgrade Id="GUID2">
<UpgradeVersion Minimum="1.98.20" Maximum="1.98.206"
Property="PREVIOUSVERSIONSINSTALLED" IncludeMinimum="yes"
IncludeMaximum="no" /> </Upgrade>
<InstallExecuteSequence>
<RemoveExistingProducts After="InstallInitialize" />
</InstallExecuteSequence>
---END OF CODE---
Now it will install over the top, but unfortunately it leaves an orphaned
duplicate entry in Add or Remove Programs which can't be removed except by
msizap.
I have a feeling I'm misunderstanding the roles of the GUIDs in the
UpgradeCode and Upgrade Id tags. Or perhaps specifying a GUID in the
Product Id of the first version has irrevocably screwed things up.
Does anyone have any suggestions on how I can make an .msi file which will
completely uninstall the first package when installing over the top of it?
